NAME
     README.epoc - Perl for EPOC

SYNOPSIS
     Perl 5 README file for the EPOC Release 5 operating system.

INTRODUCTION
     EPOC is an OS for palmtops and mobile phones. For more
     informations look at: http://www.symbian.com/

     This is a port of perl to the epocemx SDK by Eberhard
     Mattes, which itself uses the SDK by symbian. Essentially
     epocemx it is a POSIX look alike environment for the EPOC
     OS.  For more information look at:
     http://epocemx.sourceforge.net/

     perl and epocemx runs on Epoc Release 5 machines: Psion 5mx,
     5mx Pro, Psion Revo, Psion Netbook and on the Ericsson M128.
     It may run on Epoc Release 3 Hardware (Series 5 classic),
     too. For more information about this hardware please refer
     to http://www.psion.com/

     Vendors which like to have support for their devices are
     free to send me a sample.

INSTALLING PERL ON EPOC
     You can download a ready-to-install version from
     http://www.oflebbe.de/perl/perl5.html

     You will need at least ~6MB free space in order to install
     and run perl.

     Please install the emxusr.sis package from
     http://epocemx.sourceforge.net/ first.

     Install perl.sis on the EPOC machine. If you do not know how
     to do that, consult your PsiWin documentation.

     Perl itself and its standard library is using 4 MB disk
     space.  Unicode support and some other modules are left out.
     (For details, please look into epoc/createpkg.pl). If you
     like to use these modules, you are free to copy them from a
     current perl release.

STARTING PERL ON EPOC
     Please use the epocemx shell to start perl. perl integrates
     with the conventions of epocemx.

  Features of Perl on Epoc
     The built-in function EPOC::getcwd returns the current
     directory.

  Restrictions of Perl on Epoc
     Features are left out, because of restrictions of the POSIX
     support in EPOC:

     o   socket IO is only implemented poorly. You can only use
         sysread and syswrite on them. The commands read, write,
         print, <> do not work for sockets. This may change iff
         epocemx supports sockets.

     o   kill, alarm and signals. Do not try to use them. This
         may be impossible to implement on EPOC.

     o   select is missing.

     o   binmode does not exist. (No CR LF to LF translation for
         text files)

     o   EPOC does not handle the notion of current drive and
         current directory very well (i.e. not at all, but it
         tries hard to emulate one). See PATH.

     o   Heap is limited to 4MB.

     o   Dynamic loading is not implemented.

  Compiling Perl 5 on the EPOC cross compiling environment
     Sorry, this is far too short.

     o   You will need the epocemx SDK from Eberhard Mattes.

     o   Get the Perl sources from your nearest CPAN site.

     o   Unpack the sources.

     o   Build a native perl from this sources... Make sure to
         save the miniperl executable as miniperl.native.

         Start again from scratch

               cp epoc/* .
               ./Configure -S
               make
               cp miniperl.native miniperl
               touch miniperl.exe
               make
               perl createpkg.pl

               emxsis perl.pkg perl.sis

SUPPORT STATUS OF PERL ON EPOC
     I'm offering this port "as is". You can ask me questions,
     but I can't guarantee I'll be able to answer them. Since the

     port to epocemx is quite new, please check the web for
     updates first.

     Very special thanks to Eberhard Mattes for epocemx.
